The issue with the smith machine is the same as with all machines. The weight only moves in a single path, this means that (1) Each rep is identical, which causes the stress points of each rep to be identical, increasing the risk of injury, and (2) it means you don't have to control the weight, normally a weight has 3 degrees of freedom (up-down, left-right and forward-back) which means you have to stabilize/control the weight, but that's not the case with the smith machine.
Is the smith machine the absolute devil...no, but I'm pretty certain that you can find a gym with a squat rack somewhere in the Bronx...you may have to do some looking, it could be some hole in the wall, smalltime place, or maybe you know a guy who knows a guy with a power rack. You could also try posting on the EliteFTS Q&A under sick of my gym, where a common question-answer is where one person states their location, and that their current gym sucks, and another person repsonds with a good gym in that persons area. Seriously, it's not like you're in the middle of nowhere, you should be able to find a good gym.
